what you have said are new features , but it would really be great if you can look into the "What's New" section that comes with the tool(am assuming that you have the tool), guess you may get them first hand from the doc set also..
Mercury Screen Recorder. Capture your entire run session in a movie clip or capture only the segments with errors, and then view your movie from the Test Results window.
Dynamic Management of Object Repositories. Programmatically manage an action's shared object repository collection during the test run.
Enhanced Object Spy Functionality. When you hover over objects in your application using the pointing hand, you can view their properties, methods, and object hierarchy in the Object Spy. As you hover over each object, it is highlighted in the application.
Web Drag and Drop Support. You can now create and run drag and drop operations in Web environments.
Text Recognition Support for Windows-Based Environments. You can capture text from Windows-based objects using text or text area checkpoints and output value steps, or using the GetText, GetVisibleText and GetTextLocation methods.
PS: one can always download the doc set from the support site and this does not need the tool.
